Clare mixes 2 1/2
cups of water with
1/3
cup of orange juice concentrate.
—————————
How much water would she use for one cup of concentrate? (use a decimal)
—————————
How much water would she use for 10 cups of concentrate? (use a decimal)

1. 1 cup of concentrate would use 7.5 cups of water.

2. 10 cups of concentrate would use 75 cups of water.

Step-by-step explanation:

Because 1/3 cup of concentrate is mixed with 2 1/2 cups of water, to find how much water one cup of concentrate would use, you would have to multiply both 1/3 and 2 1/2 (2.5) by 3. Then, you get 1 cup of concentrate equals 7 1/2 (7.5).

To find the answer to the next question, simply multiply by 10.
